Quite easy by dirt roads branching northwards off main Iringa-Morogoro road and vehicular access to area where artisanal mining is taking place. Access to other parts of the project area is however likely to be difficult especially since most of the area is quite mountainous.
Regional & Project Geology:
The licenses areas have active artisanal mining for Cu and have shown that the veins which host the Cu mineralisation carry grades of between 3-27% Cu (in high grade random grab samples collected).
The area is underlain by Paleoproterozoic (Usagaran) rocks which form a distinct magnetic signature in the regional geophysical data and which are interpreted to indicate a complexly deformed package of meta-volcanic and meta-intrusive mafic-ultramafic rocks prospective for base metal mineralisation.

The Kinusi Project is underlain by complexly deformed Palaeoproterozoic (Usagaran) rocks considered prospective for base and precious metals mineralisation of various styles, volcanogenic massive sulphide (VMS), mafic-ultramafic intrusive nickel-copper sulphide (M-UM Ni-Cu) and possibly Iron Oxide Copper Gold (IOCG).
There are numerous Cu and Fe occurrences within and around the Project Area which are possible indicators to larger mineralised systems in areas on the published 1:2,000,000 scale geological map of Tanzania as well as from other sources.
The main areas of interest within the Project Area are in the vicinity of Kongwa village and the Kinusi-Tagawana area. Infrastructure is very good in the northern Kongwa area which straddles the main sealed road from Dar es Salaam to Dodoma. The southern KinusiTagawana area is accessible by unsealed (dirt) roads and tracks in general, but mountainous topography east of Kinusi village in particular will make fieldwork challenging.
There are a number of Cu and Fe occurrences shown within and around the Kinusi Project Area on the published 1:2,000,000 scale geological map of Tanzania as well as from other sources.
The general prospectivity of the area is based on the following factors:
The occurrence of major structural domain boundaries separating the Archaean Tanzanian Craton in the west from the Palaeoproterozoic Usagaran Orogenic Belt as well as the Neoproterozoic Mozambique Belt in the east. The Kinusi Project Area in general lies within the Usagaran Belt.
The regional magnetic signature of the area suggests a complexly deformed sequence including prominent remanently magnetised bodies or packages of rocks which are associated with known occurrences of Cu, Fe and Ni.
The high grade metamorphic rocks of the Palaeoproterozoic Usagaran Belt are believed to be prospective for base metal mineralisation of the volcanogenic massive sulphide (VMS) variety (i.e. Cu-Pb-Zn +/- Au +/- Ag) and many of the Cu occurrences in the area are seen as prospective ‘smoke’ of potential larger deposits in the area.
Iron Oxide Copper Gold (IOCG) type mineralisation in the area is also considered a valid target; particularly associated with the numerous Fe and Cu occurrences and the magnetic signature evident in the southwest of the area near Konse, Winza and Massa.
There are known occurrences of Ni-Cu(-PGE) mineralisation associated with MUM lithologies in the Lufusi area.
The age of the targeted M-UM intrusive rocks is uncertain and could be Palaeo- to Meso- to Neoproterozoic in age. Irrespective of age, the structure, tectonic setting and mapped M-UM bodies of the area in general suggests the area is prospective for M-UM hosted Ni-Cu mineralisation. Significantly the presence of Ukingan Group rocks in the area means that Mesoproterozoic M-UM rocks similar to Kabanga are possible, however the general interpretation is that the M-UM rocks of interest are probably Palaeoproterozoic in age.
